Most computers have two or more ‘registered’ user accounts on them. Having multiple user accounts on one computer is very useful, but it can cause some problems, sometimes.

This time, we’re going to talk about the problem which prevents you to log into a user account, showing you the error “System running low on resources – Cannot log on as new user.

How can I fix System running low on resources error on Windows 10?

  1. Make sure you closed all programs
  2. Change Power Settings
  3. Clean boot your computer
  4. Scan your computer
  5. Fix computer memory issues

As you noticed, this error shows mainly on computers with multiple user accounts. And it appears when you switched from one user account to another, without closing all running programs.

So, if you didn’t close all running programs, before you switched to another user account, there’s a chance that error saying “System running low on resources – Cannot log on as new user” will appear on the next reboot.

As you left these programs running, they’re now using your memory, and you don’t have enough memory to ‘run’ the next user account.

This error usually appears on computers with lower memory, and it was more common in previous versions of Windows, but if your computer is barely compatible with Windows 10, it could show up on your machine, as well.

So, let’s see what can we do to eliminate this error, and log in to the new user account, normally.

Solution 1 – Make sure you closed all programs

As I told you, this error probably appeared because of running programs that use your memory resources. So the first logical step towards solving this problem is to close these programs.

So, before logging to the other user account, go to the user account you were using last, and see if there are any programs left running.

When you make sure you closed all your programs on one user account, go to Log out (not Switch accounts), and when you’re successfully logged out, try to log in to another user account, again. You shouldn’t have any problems this time.

Solution 2 – Change Power Settings

There’s one other, similar cause of the problem. This is related to laptops, and it depends on how your computer is set to react before laptop lid is closed.

First thing first, you MUST wait until you’re logged of to close your lid, don’t close your lid while still logged on, because there’s a big chance this error will appear.

Also, your laptop’s power settings are probably set to put your laptop to sleep, or hibernation when the lid is closed. So, if you really can’t wait to close your lid, before you log off, you should do a couple of changes in your Power Management settings.

Here’s exactly what you need to do:

  1. Go to Search, type power options, and open Power Options
  2. Choose What closing the lid does
  3. Choose Do Nothing when the lid is closed
